Update on my mum's 2018 Vauxhall Crossland X, after an oil consumption test it's been found to have used 1 litre of oil for 585 miles. Topped up with 2 litres of oil today and the engine is now smoking badly and rattling. Perry's Doncaster advised that the car needs a new engine. 8 years old. Full main dealer MOT and service history. 61,354 miles on the clock and the engine is buggered. WTF?!
